Seismic hybrid isolation system using sliding bearings and multi laminated rubber bearings is one of the practical isolation devices, because it can make the primary period of horizontal responses comparatively long easily, not changing that of vertical responses. However, there have been few studies on frequency characteristics of structure with this hybrid isolation system, which is important for seismic design of equipments and/or piping system attached to the structure. This paper shows that we can evaluate frequency characteristics of structure with the hybrid isolation system well, through the simulation analyses for results of shaking table excitation test.
